Several instances of Logstash

Good Day, Colleagues!
i'm getting to make two instances of Logstash. Actually two services with two different configs.
I'm trying to do this, but the second service doesn't transfer data to kibana, although if i start it from cmd it works fine!
I can't realize why. I'll appreciate for any help )

I'd start by enabling more verbose logging for Logstash by starting it with --verbose or --debug.

Thank you, Magnus!
It was a regular magic. We've solved the problem. It was about permissions to files and folders. :smile:
